Hi,
I (student) was doing a timed quiz and used my phone (mobile app) to view the questions while I was using my laptop to work on the answers. I was left with 10 minutes left for the quiz and when I tried opening the quiz on my laptop, it said that the quiz was muted.
I've also done this for a few other tests before and didn't have any issues with reopening on another device.
Is this a glitch or a feature?
